Concerns development of accessory dwelling units and related regulations.*

This bill requires New Jersey municipalities to allow accessory dwelling units (ADUs) - secondary housing units on the same lot as a primary home - as a permitted use, rather than restricting them. It sets specific rules: ADUs must be at least 300 square feet, located at least five feet from property lines, not exceed the primary home’s height, and cannot be used for short-term rentals (less than 30 days). Homeowners seeking to build ADUs for personal use (e.g., family members) or as a rental for long-term stays would be directly affected, alongside municipalities required to update zoning ordinances within 90 days of the law’s effective date. The bill aims to expand housing options by leveraging existing residential lots without altering neighborhood character.
